New well, professional water analysis ... need advice!

Building a new house near a small town in S. Colorado. The area has a history of "problem" well water - hardness, iron, methane, etc.

House still under construction; plumbing roughed in. Water flows from the well at 2.5 gal/min. into an 1800 gallon cistern. The house has 4 bedrooms 3.5 baths; normally only 2 full time occupants, but we expect visits from family and other guests. Water analysis (below).

My basic problem - I would prefer not to rely only on someone selling softening equipment to tell me what I need or what my options are. And water treatment professionals and services are limited in my area.

I'm not looking for the cheapest solution or specific brand recommendation, but rather the type and degree of treatment I should consider. I'm reasonably handy and don't mind getting involved, but I'm new to water softening and welcome any advice.

Here is the well water analysis done by an independent lab (most measurements are mg/L, ND = not detected):

The water IMO contains a lot of sodium which I think you should address. The hardness is about about 4 GPG which is considered hard water. Other than that, the water seems to be good. Are there any smells to the water?
